MACHINE FOB AND METHOD OF FORMING RING TRAVELERS.

Application filed October 27, 1921, Serial No. 510,919. Renewed June 21, 1924.

To all whom it may concern.

Be it known that I, PHILIP C. vVnnr- WORTH, a citizen of the United States, re siding at Providence, county ofil rovidence, State of Rhode lsland, have invented certain new and useful Ii'nproven'ients in Machines for and Methods of Forming Ring Travelers, of which the following is a specification.

This invention relates to a machine for and method of forming the ring travelers illustrated in the patent to Philip Call ent worth, No. 1,415,069fgranted May 9, 1922, to which reference is made as indicatingthe particular type of traveler involved herein.

The ring traveler illustrated in said VVentworth patent is of-standard type, but is provided through itsbow portion with a longitudinally disposed ventilating slot which permits a draft through the traveler effective to prevent the accumulation of lint thereon.

The production of such travelers in commercial quantities and in the several standard sizes and thicknesses which the trade requires It is of the utmost importance that the ventilating slot be located in each traveler, and in each size of traveler, at exactly the center of the traveler bow, since any variation in the location of such slot will destroy the balance of the traveler. The slot cutting mechanism andthe stock :t'eed, cutting and bending mechanisms must therefore not only operate in properly timed relation, but must be capable of such relative adjustment that the slots will be accurately cut in travelers of a different sizefrom that which the machine had been previouslyforming.

To the end therefore of adapting such existing equipment to theproduction of the new type traveler in all the usual sizesand thicknesses of the old type traveler, Ihave devised mypresent invention.

The construction and operation ofmy invention, together with a selected'eml'iodiment which well illustrates the principles involved and is initself' a form which I havefoundsatisfactory under actual working-conditions, are described and shown in the accompanying specification 2l11(l,(l1'21W ings, and the characteristic features of novelty are, particularly pointed out inthe appended'claims.

Throughout'thc specification and drawings, like reference characterspare correspondingly employed and in the drawings:

Figure 1 is a front view of a ring traveler forming machine equipped in accordance with my invention.

Fig. 2 is a rear :view thereof.

Fig. 3 is a plan view.

Fig. 4 is an end VlGWfIOlll the right of Fig. 1.

Figs. 5, 5 and 15* are diagrams illustrating the action of the stock punching, feed, cutting and bending mechanisms.

F ig, 6 is a section showing the reciprocating anvil over which the stochis cut and bent! Figs. 7 to 16 inclusive are detail views of the punch and die mechanism for cutting the slot in the ringtraveler bow, and

Fig. 17 is a diagrammatic illustration comparative of the relation of stop and punch for two sizes of traveler.

I have indicated at 1 a suitable frame work and at 2 a cam shaft journaled longitudinally thereof and provided at one end with a .fastpulley 3 and a loose pulley l over which a driving belt 5 is adapted to be shifted to connect and disconnect the drive.

The stock S is intermittently fed in strip form by a pair of opposed, oppositely revolving feed rolls 9 between which the strip isgripped. In advance of said feed rolls is a punch and die mechanism 8 for cutting the slots S at definitely spaced intervals in the strip so that each slot comes exactly at the center of the traveler how when the travelerblanks B are out along the dotted lines, Fig. 17, and the blankslilent to ring traveler form, as indicated in 5, 5e, 5 and 6.

From the feed rolls 9, the slot provided strip S passes along a guideway 10 until its freeend contacts a. stop 100 adjnstably mounted in the line offeed 0f:the strip.

Mounted in advance of the stop 100 is a horizontally reciprocating anvil 11 over which the stock is severed by the cooperation of a vertically reciprocating swaging mechanism 50 and stationary cutters 60. The individual blanks are then bent to ring traveler form by a pair of oppositely disposed reciprocating bending dogs 70.

The punch and die mechanism 8 for slotting the stock is detailed in Figs. 7 to 15 inclusive. Referring to these figures I have indicated at 15 a bracket which is attached to one of the standards of the frame work 1 and is provided in its horizontal portion 15 with a slideway 16 along which is adjustable by means of a feed screw 17 a casting 18. The slide 18 has a vertical extension 19 constituting a slideway for the vertically reciprocating punch block 20 of the punch and die mechanism and beyond said slideway is offset and extended upwardly, through which the cam shaft 2 extends.

Fast within a recess at the lower end of the punch block 20 is a punch 21. The punch block is reciprocated in its slideway from the cam shaft 2 by a cam 22 thereon operating against the head 23 of a connecting rod 24 to which the upper end of the punch block is fastened.

Below the guideway 19 the slide casting 18 is recessed as shown inFig. 16 to receive a die block 25 which is fastened to the casting, as indicated at 25 The block 25 has a central chip-clearance slot 25 and adjacent said slot is formed with spaced longitudinally extending lugs 25 providing a guideway for the die 25. (Figs. 11, 12 and 13.)

The die 25 is sectional, consisting of two sections detachably connected to each other by the pins 25. The die sections are each centrally cut away along their opposing edges to provide a slot 25 adapted to align with the punch 21 and with the chip clearance slot 25 of the block 25. The die is formed to fit the guideway 25 and is adjustable longitudinally therealong, the adjustment being held by a set screw 25 As here shown, one face of one of the die sections is beveled as indicated at 25 to fit correspondingly beveled face of one of the lugs 25 constituting the guideway for said die.

Surmounting the die is a pair of spaced guide strips 26 constituting a guideway 27 (Figs. 10 and 16) for the stock S. The opposed edges of each guide strip 26 are centrally cleared away as indicated at 28 (Fig. 10) to provide a slot alined with the punch 21 and with the opening 25 of the die 25.

The guide strips 26 are adjustably mounted in an angularly-formed holder 25 (Fig. 9) which is clamped within the recess of the slide casting 18 by clamping screws 250. The guide strips 26 have downwardly extending lugs 26 which enter transversely disposed slots 26 in the divided bottom wall of the holder 25. Set through the holder and guide strips is a plurality of adjusting screws 26 by means of which the strips 26 may be relatively adjusted. (Figs. 15 and 16.) r

The screw 17 permits the slide 18 carrying the punch and die to be moved towards and from the anvil 11 whereby to locate the slots S formed in the strip S by the punch exactly at the center of the bow of the traveler when the strip S is cut into blanks B by the cutters 50 and 60 and the blanks formed over the anvil.

The feed rolls 9 are intermittently actuated from the cam shaft 2 by a cam 30 on said shaft which actuates a cam lever 31 which is pivoted between its ends at 32 to the frame work of the machine and is under spring control as indicated at 44, Fig. 2. The lower end of the lever 31 is provided with a gear segment 33 meshing with a pinion 34 on a stub shaft 35. (Fig. 2.) The rotation of the stub shaft 35 is transmitted to the feed rolls by a gear 36 on said shaft which meshes with a gear 37 on the upper feed roll shaft. The gear 37 mes-hes with a gear 38 on the lower feed roll shaft, (Fig. 2), whereby to rotate the feed rolls in unison and in opposite directions.

Fast on the stub shaft 35 is a ratchet wheel 39 with which cooperates a pair of pawls 4O pivoted in recesses cut in the outer'face of the gear 36. V

The lower feed roll shaft is mounted in a floating bearing and is normally urged towards the upper feed roll shaft by a coil spring 41. (See Fig. 1.)

The swaging mechanism comprises a finger 50 and a pair of swages 51 disposed one on each side of the finger 50. The finger and swages are mounted in a slide block52 (Fig. 1) which reciprocates vertically in a slideway 63 mounted on the framework of the machine, being actuated from a cam 64 on the cam shaft 2.

The anvil 11 is reciprocated horizontally across and slightly below the path of the stock feed by a cam 61 on the cam shaft 2, which actuates a cam lever 62 that is pivoted at 63 to the framework 1 (see Fig. 2) and through the links 64 reciprocates the plunger 65 which carries the anvil. Said plunger 65 is suitably guided in a guideway 66 (Fig. 6) extending from front to rear of the framework.

As the finger 5O descends the anvil is ad vanced so that the finger holds the stock on the anvil (Fig. 5) while the swages 51 move past the anvil and cut the stock over the stationary cutters 60 (Fig. 5"). time, a pair of oppositely disposed bending dogs 70 mounted below the cutters 60 are advanced towards the anvil to bend in the At this extremities of the blank B, thereby forming the horns of the traveler (Fig. 5).

The bending dogs are adjustal'ily mounted at 71 in suitable blocks T2 and are actuated from the cam shaft 2 through a pair of cam levers 73 (Fig. 2) which are pivoted between their ends at 7 1 to the framework and at their upper ends have :cam rolls 7'5 on the cam shaft. The cam levers 73 on either side of their pivots 7% are under spring control as indicated at T8 and 79, Fig. 2.

After the traveler blank is cut and formed, the anvil 11 is withdrawn, stripping the formed traveler from the anvil and "allowing it to fall, as indicated in Fig. (5, to the .bottom of the machine.

When the parts are adjusted to cut travelers of the "size and length indicated at AA in the diagram =01 Fig. 17 there is of course a determinate --number or traveler blanks between the slotting station 8 and the cutting and forming station 5070.

will be cha-nged owing to the increase or decrease (as thecase maybe) in the length or .the new blanks. In order to take care of this variation in both number and length of the intervening blanks, so that the slots S will be located exactly in the center of the traveler bow for the new size of traveler, the entire slotting station 8 is adjusted by means of the feed screw 17 towards or from the relatively fixed cutting and bending station until the proper relative spacement is found for the particular blank length to be cut.

Although Ihave described and illustrated my inventionin its adaptationto the formation of a ringtraveler of the horseshoe type, comprising a pair of terminal horns and an intermediate connecting how, it will be understood that such treatment is purely illustrative and in noway limiting, and that the vertical type of ring traveler known as a twister traveler and shown in my prior Patent No. 1,415,072, granted May 9, 1922, may also be produced upon my machine. The term ring traveler as used herein, is therefore to be construed broadly as meaning any traveler, whether for ring spinning or twisting which travels about a ring.
